OK so I'm running into an issue with the timing belt change. Here's what happened:
Is that the smart way to do it? These tools should only go on in one position, so it seems like if I can get all three parts locked back in, I should still have proper timing. Or am I totally hosed?
Side note: the eLearn manual has nothing extra to add - even the procedure for dismantling the engine says to lock the cams in place before separating the head from the block, then on reassembly refit all the timing tools before installing the belt. This makes me think there are no other timing marks, even under the valve cover, and that as long as I have the locking tools fitted correctly, everything should be lined up.
- I followed the procedure exactly up to fitting the new belt and setting the tensioner at max tension. The only variation here is that I could only loosen the intake cam pulley bolt. I ruined two T55 sockets trying to pull off the exhaust pulley bolt, but I was careful and did not strip the bolt. So I only had the intake pulley loose when fitting the new belt.
- So here's where I screwed up: after I set the tensioner at max tension, I removed the locking tools without retightening the intake cam pulley bolt. As soon as the tools came off, the pulley rotated, the intake cam moved a bit and the tension went completely out of the belt.
- As soon as the locking tools were off I realized the mistake and tried to correct it by refitting the locks. I did not attempt to move the crank at all. I can refit the exhaust cam lock by just slightly bumping the cam to get the bolts to thread in, however it's clear that both the crank and intake cam have moved slightly. Based on my pictures it looks like the intake cam moved by about 5-10 degrees, and the same for the crankshaft (based on marks I made on it).
